When a user dials a number on a phone that is registered with Cisco Unified Communications Manager (CUCM), the phone sends a signaling message to the CUCM requesting routing information for the dialed digits. The CUCM then analyzes the dialed digits and attempts to match them to a configured route pattern.

The default timeout before the dialed digits are sent to CUCM for processing is 15 seconds. This means that the phone will wait for 15 seconds after the user has dialed the digits before sending them to the CUCM.

During this timeout period, the phone collects additional digits dialed by the user and sends them as a complete string to the CUCM at the end of the timeout period. This feature is known as digit collection or digit timeout.

However, it is important to note that this timeout value can be configured on the phone or at the CUCM system level, which means that the default timeout value may not be the same in all deployments.

In summary, the default timeout before a dialed number is sent to Cisco Unified Communications Manager is 15 seconds, but this value can be configured and may vary depending on the specific deployment.
